BATTERY-CHARGING" I Application 'filed September This inventiona'elates to electrical systeamsand more particularly to battery charging systems. I r

An object of the present provide means for throwing a charged bat-Q tery into an electric circuit foruse and syn opposite direction, whereby af'battery con f trolled by one switch can be thrown into the charging circuit .whendischargedand the battery controlled by theother switch thrown into the load circuit.

V ith these andother Objects inviewthe invention consists in, the novel construction arrangement and formation, of parts, as will.

be hereinafter more specifically described, claimed, and illustrated in the accompany.- ing drawings in which:

Figure 1 is a diagrammatic View showing.

: the novel battery charging system, the control switch being shown. in tull lines in its neutralapositien andn dotted lines lnbattery charging position, and

Figure 2 is a top plan' View illustrating the novel means employed for operatively connecting gether, e p

Referring to the drawings in detail, whcrein similar-reference characters designate corresponding parts throughout the several Views the letter A generally indi-T cates the lmproved system, which comprises.

, an electric generatorb which can be operated in any desired way such as by a water wheel 5. The water wheel 6 can be of any desired character and the same is provided with a water inlet 7 and a water outlet-,8. The flow of water throughthe inlet 7 canjbe controlled by a valve'9 which can be automatically or manuallyoperated asdesired.

The generator is provided with'the lead and return wires 10 and 11. The wire 10 is electrically connected to one jaw 12' of a pair of jaws 13 arranged on one side of a deubleknife switch 14, On the other side with any desired type of operating handle invention is to a pair of control switches to.

a, 1926. Serial No.133,471.

16. The return wire ll is electrically con nected to the'other jaw 17 of the pair of aws 13. The battery to be charged is indicated by the referencecharacter 2-1 and the,

terminals thereof have connected thereto electric conduit wires 22 and 28" which are electrically connected to the bladesof'the switch 14.

When the switch 14 is in eng'ageinentv with the contact jaws 12'and 17 ot'the pair of jaws 13 the current will flow from the generator 5 to the wire 10 jaw, 12, one blade of the switch, throughthe TVlI'Q'28, battery '21,

wire 22', through the other blade of the switch 14, jaw 17.

On each side of the knife switch 14 are pulleys 24 "and- 25.. The pulley 25 has trained around the same stiff cable 26 one end Of which is connected with one-arm of a bell crank 27 which is rockably mounted at its angle as at 28. The opposite arm of the bell crank 2'? has connected thereto a rod" 29, which can constitute a hand pull.

When the battery becomes charged the bell crank 27 canrbe pulled downward by hand or other suitable means causing a pult on the cable 26, which has its end opposite to the bell crank '27 connected with the I handle of the switch 14. This will 'pu ll'the switch'away. froin'the'pair of contact jaws v 13 and move the same into engagement with the pair ofcontactjaws 15. Thus the circuit to the battery 21 is broken and further charge, at this time, is prevented. The

battery can now be connected into the circuit for use and the :pair of contact jaws 15 are arranged inthis load circuit. circuit includes the lead wires 30 and 31 the inner terminals of which are connected to the pair of jaws 15. These wires are led to the desired place of use of the current. A pull rod 35 is connected with one arm of a bell crank 36. This'bell crank 36. is rockably mounted at its angle on the opposite. side of the switch14 from the bell crank 27. One terminal of a stiii cable 37 is connected to the other arm otthe bell crank 38 and this cable is trained over the pulley 24 and has its opposite end secured to the handle 16 of the throw switch 14.

When the battery 21 is in the load circuit,

This load the switch 14 is in engagement with the of jaws 15, as heretobetore stated andthe. current will flow from the battery through the wire 22, one blade of the switch 14, one

jaw of the pair of jaws 15 through the wire 30, back through the wire 31, through the other jaw of the pair of aws 15, through the other blade of the switch let, wire 23, back to the battery 21. As the battery becomes discharged, the bell crank 36 is pulled down by hand or other suitable means and the cable 37 will throw the switch 14: from out oli engagement with the pair of jaws 15 into engagement with the pair of jaws Conseqljlently the battery will be thrown out of the load circuit into the charging circuit. Due to the connection of the cables 26 and 37 with the switch lever 14 movement oi one hell crank will be tran mitted to the other as is olwious.

The invention also comprehends the use of two storage batteries and these batteries are so arranged that when one is being charged the other will be in use and discharging. The charging of the battery and the discharging of the other battery is so balanced that the ate of charge and discharge will be equal, so that one battery will be ready to be recharged as the other is ready for use. To accomplish this 1 pro vide a second switch ll) which is arranged in longitudinal alinement with the switch 1% and this switch 4d) is of the same construction as the switch 11- and arranged in a charging circuit and discharging circuit. Thus on one side of the switch ll) is a Pair of contact jaws all for the charging circuit and a pair of contact jaws 42 on the opposite side tor the load circuit. Rockably mounted at a point equidistant its ends between the switches let and s0 is a double ended lever L3. The opposite terminals of the double ended lever L8 are provided with longitudinal slots 44 in which are slidably and pivotally mounted pins 15 and 46, which are carried respectively by the switch ll and the switch l0. Thus when the switch let is moved into engagement with the pair of jaws 13 the switch will be moved into engagement with the jaws 42. From this arrangement the battery controlled by the switch 1 1.- will be connected with the charging circuit, whilethe battery controlled by the switch ll) will be connected with the load circuit. hen the switch M- is moved into engagement with the jaws 15 the switch 40 will be moved into engagement with the jaws 41 and thus the battery controlled by the switch 14: will be connected with the load circuit, while the battery controlled by the switch 40 will be in the charging circuit.

Changes in details may be made without departing from the spirit or scope oi this invention, but:

lVhat 1 claim as new is:

In an electric battery system, a switch including a throw handle having a pair of movable blades, a pair of contact jaws arranged on each side of the throw handle, a second switch including a rocltable throw handle including a pair of blades, a pair of jaws arranged on opposite sides of the second mentioned switch, a. double ended lever rockably mounted at point. intermediate its ends, and means operatively ccn necting the opposite ends oi the double ended lever to the throw haiulles, whereby upon movement of one throw handle the other will be operated therewith and in a direction opposite thereto.

In testimony whereof I alli); my signature.
